BOTTLE-CAP.

Application filed January 15, 1919.

To all whom it may concern:

Be it known that I, AMos L. FOREMAN, a citizen of the United States,residing in York, Pennsylvania, have invented certain Improvements inBottle-Caps, of which the following is a specification.

The object of my invention is to so construct a closure for milk bottlesand the like as to effectually prevent exposure of the contents of thebottle to contamination during storage or transit but permit readywithdrawal of the contents of the bottle when .desired, also Withoutsuch exposure.

This object I attain in the manner hereinafter set forth, referencebeing had to the accompanying drawing, in which- Figure 1 is a verticalsectional view of the upper portion of a milk bottle provided with asealing cap in accordance with my invention, the section being taken onthe line 1-1, Fig. 3, and showing the cap as it appears when the bottleis in storage or transit;

Fig. 2 is a similar view taken on the line 2-2, Fig. 3, but with thesealing cover removed, in order to illustrate the manner in which'thecontents of the bottle are withdrawn without exposure to contamination;

Fig. 3 is a top view of the bottle shown in Fig. 1, and

Fig 4 is a similar view of a bottle having a cap with modified form ofsealing connection between the same and the cover.

In the drawing, 1 represents the upper portion of the neck of the bottlehaving the usual recessed mouthwith cap seat at the base of the same, asusual. The closing cap 2 which rests upon this seat is of sufficientthickness to possess the. desired strength and rigidity and has formedin it two openings 3 and 4, the opening 3 being the larger of the twoand being intended for the insertion of a suction tube 5, as shown inFig. 2, whereby the contents of the bottle or any desired portion of thesame can be withdrawn without removing the cap 2 and also without undueexposure of said contents.

On the upper face of the cap 2 and surrounding the openings 3 and 4therein is a band 6 of adhesive material, and above the cap 2 andsecured thereto by said band of adhesive material 6 is a cover 7 ofparchment paper or other tough and flexible material, which has at eachside a wing 8, these wings being at right angles to the band 6 andprojecting slightly beyond the mouth of Specification of Letters Patent.

the bottle so as to provide means whereby the cover 7 can be readilygrasped and torn from the cap 2 when it is desired to release the sametherefrom, the band 6 of adhesive material surrounding the openings 3and l and serving, when the cover 7 is in place, to secure the same tothe cap so firmly as to effectually seal the openings against theadmission of air.

After the cover 7 has been secured to the cap 2 by the adhesive band (3,the cap and cover are dipped in a bath of melted paratlin wax, whichserves not only to provide a waterproof coating for all accessiblesurfaces of the cap and cover, but, when cooled, also serves to unitethe edges of the cap and cover and also the upper surfaces of the capand the underside of those portions of the cover between the edges ofthe cap and the edges of the band 6, thus providing-an additional sealfor the openings 3 and 4-, which seal can, however, be readily broken bypulling upon either of the wings 8, so as not to interfere with thetearing of the cover free from the sealing band 6 of the cap when thestrain is exerted upon the latter.

The suction pipe 5 is preferably made of paper coated with paraffin orotherwaterproofing material, and when sealed in a sanitary envelop, suchas that in which tooth picks are now served, it accompanies the jar ofmilk when the same is sold and thus provides for the sanitary serving ofthe milk as well as the sanitary packaging of the same while in storageor transit, the milk being protected from undue exposure during serviceand being also free from contamina tion by contact with the frequentlyunsanitary surfaces of glasses or cups into which it is ordinarilypoured from the bottle and from which it is drunk.

Instead of providing the upper face of the cap 2 with a band of adhesivematerial extending across the cap and of a width greater than thediameter of the opening 3 said cap may have applied to its upper face,as shown in Fig. 4, circular bands 6 of adhesive material surroundingthe openings 3 and 4, and serving to secure the cover 7 thereto so as toseal said openings.

If the opening 3 in the cap is sufliciently larger in diameter than thetube 5 to permit inflow of air around the tube while the milk is beingwithdrawn through the same, the opening 4 in the cap may be dispensedwith,

but it is preferable to fit the tube 5 snugly to the walls of theopening 3, in which case the air inlet 4 is necessary.

The narrow bands 6, 6 of adhesive material surrounding the openings 3and L in the cap are of a different character from the paraflin adhesivewhich unites those portions of the cap and cover outside of the limitsof said bands 6, 6 the paraiiin seal being of a readily frangiblecharacter while the adhesive 6, 6, although permitting separation of thecover from the cap when suiticient force is applied, preventing suchseparation under the strains to which it is subjected in the ordinaryhandling of a bottle.

In my claims I have, therefore, indicated this difference bycharacterizing the adhesive 6, 6 as non-frangible, meaning thereby thatit is not so frangible as the paraffin seal used in associationtherewith, and hence provides for a more secure sealing of the openings3 and 4 than would the paraffin seal alone.

I claim:

1. A milk bottle cap having an opening therein for the reception of asuction tube through which the contents of the bottle can be withdrawn,said opening being surrounded by a band of non-frangible adhesivematerial, and said cap being provided with a sealing cover normallyheldfiin place thereon by said non-frangible adhesive material so as toseal the opening therein but which can be freed from connection with thecap when it is desired to uncover said opening.

2. A milk bottle cap having an opening therein for the reception of asuction tube through which the contents of the bottle can be withdrawn,said opening being surrounded by a band of non-frangible adhesivematerial, and said cap being provided with a sealing cover normally heldin place thereon by said non-frangible adhesive material and by afrangible seal beyond the limits of the same, which latter seal is thefirst to be broken when the cover is withdrawn.

In testimony whereof, I have signed my name to this specification.
